T0 on whom it may concern:

Be it known that 1, Ln: CHAMBONNAUD, a citizen of the Republic ofFrance, residing at Limo es, France, have invented certain new an usefulImprovements in Stenoaphic Machines, of which-thefollowing is a 11,clear, and exact specification. This invention relates to certain newand useful improvements in stenographic maro chines; and it has for itsobjects, among others, to. construct a machine ermitting of plain andclear stenographytfiat is to say, of Writing speech not by means ofspecial signs'requiring for their typing or printing, I 5 as well as fortheir reading, a special initiation, but sim 1y by inscribing thehonetic sounds or syl ables of the words wit out respect to the orthoaphy. In order 'to accomplish this rapi lythat is to say, to be able totype or print instantaneously all the elements composing a word or asyllablean arrangement should be used possessing several printingointswhich Wlll be put into action by stri ing at the same time several keys,whence it is necessary to adapt to the machine a specialkeyboarddetermined by the maximum number of printin -points employed and by thelanguage in W ich it is desired to stenograph. According to thisprinciple the following English sentence, Short writing is indispensableto business peoIple,,'

for instance, could be reproduced as fol ows: Shor t ri ting iz in dispen so bl tu biz nes pee Ip1.

5 T e accompanying drawings represent several forms of carrying intoeffect such a machine and its acce ssorles, in which Figure 1 is a viewof the type of keyboard.

Figs. 2, 3, and 4 are diagrammatic views of three types of keyboards,and Fig. 5 is a diaaromatic plan viewiof a of machine. *igs. 6 to 10 aredetail views." Fig. 11 is a diagrammatic side View of the interior partsof a t e of machine, and Figs. 12 and 13 .45 show different methods ofputting into prac tice the controlling-levers of. the typing or printinghammers. I Fig. 14 shows in perspective the arrangement of the inkingand typing or printing ribbons. 15 1s a diagrammatic plan view of a mod'catlon of the machine, and Figs. 16 and 17 show an arra'n' ement ofkeyboard for only one hand.- r is stenographic machine consists,essentially, of a, complete ke board, two to four ammers, each groupsaving-its own printing-point, a. printingribbon, an inking device, andlevers connected to keys and transmitting the movement to thetype-carrying hammers.

Before describing the details of construction of the said machine itwill be convenient to specify the construction of the differentkeyboards which can be used.

Su posing the honetic elements are divide into two c asses anddesignated as cf (the phonetic consonants) and v, (the phonetic vowelsor di hthon s,) the syllales will be, for exampe, of the form c,

c, v, ct hat is to say, for elements; To print these four elements atonce, amachine must be used with a keyboard controlling fourrintingpoints at once. This theoretic keyfioard is represented in Fig.1, and according to the number of phonetic elements to be composed acomplete-keyboard will be adapted withfour, three, or two sep aratesubsidiary keyboards.

In Fig. 1, 1, 2, 3, and 4 re resent the keys.

For the printing of the nglish language, for instance, a completekeyboard can be used, as shown in Fig. 2, composed of four separatesubsidiary keyboards 5, 6, 7, and 8, the whole of the keys of which willpermit of the printing of all the consonants or joint consonants, aswell as the vowels and diphthongs b, d, f, g, t, v, a, e, i, o, u, ei,ou, oi, ing. In the drawing each key carries its own indication, which1t will-cause to be printed, andthe whole keyboard, Fig. 2, having aboutfifty-five keys, can be arranged, if desirable, similar to the keyboardof a piano. It will be composed, first, of the keyboard 5 of jointconsonants on the left, containing twenty-two keys; secondly, of thekeyboard 6 of the modifiers with four keys; thirdly, the vowel-keyboard7, with eleven keys, and, finally, the keyboard -8 of modifiers of thesecond series, with eighteen keys. By theterm modifier I mean either aconsonant or a vowel following and modifying the sound of the firstvowel or consonant pronounced. It being understood that in a syllablewith four elements 0, c, v, c the first consonant constitutes the oneprincipally pronounced, the second only playing the part of the modifierof this pronunciation, the vowel .being also a principal element and thecon- -sonantfollow1ng only serving to modify the sound of this vowel. Itwould alsobe possible by using an arrangement already adopted in certainty e-writing machines to adopt a keyboard suc as represented in Fig. 3,containing twenty-eight keys 9, each of which represents two elements,and four change-keys 10. The latter permit of presenting to theprinting-point either one of the two phonetic elements which representthe ordinary keys. Proceeding on the same principle, a keyboard can beadopted as shown in Fig. 4, which onlyeft, and theother four willconstitute the keyboardofthe vowels and. the -most .fre-

' qnent vowel-modifiers. "The change-keys will be operated bythe twothumbs and can also .be .provided with. arresting-stops, as .in certainother writing-machines, in order to present on=theprinting-point for acertain time, according to, desire, the second or third phoneticelementof the ordinary keys.

*tFig. 5 represents a diagrammatic plan view dfa stenographic machineprovided with. a keyboard such as is shown in Fig. 3. On a framework 13are supported at suitable points printing-levers 14 of difl'erent types,

some of which areseen in Figs. 11, 12, and 13, .saidlevers carrying attheir extremities ordinary keys 9. The printing-levers 14 are connectedby convenient supports to the levers .15, carrying characters, thelatter acting on .theiinking device, which may be a ribbon 16 (see Fig;14.}similar to those used in ordinary type-writing machines, actuatedbya movement from left toright and wound for this purpose on spools. 1718. (See Fig- 14.) This ribbonpasses at 19 before the printing- ;ribbon20, (see- Fig. 14,).- a ribbon of paper identical with these used on theMorse telegraphic instruments, moving-from right to left, ,which isunwound and wound cnthe spools 2 1'. The spools are controlled either bya clockwork-movement provided for this purpose or by a spindle-23 andgearwheels 24,;utilizing the depression ofrthe keys of-the principalkey- .board,.or any other. known manner as al-,

ready used in .certain typewvriting machines. The inking-ribbon andutsmanner. of. actuationis that common-in the Remington typewriter.

As. already explained, .thk63b0fi1'd5 rep- ;resented in Figs. 2. and:Bhavefour printingpoints, .forinstance, f1" 0 kasseeltm Fig.6, so thatwhen the keys correspondingtof, fr/Y a, fki. are strucksimultaneouslythehammers ca :theccrrespcnding characters are suitablyp acedand.print:thephonetic syllables frak" of .the .wordfractional, forexample. In the simple keybcard, such as these represented E1g2r2;thereis only onephonetic elementfcreachake ran-mnsoquence each hammercarries on y one character. Fi 8 shows a front view and section of one.of t iese hammers 25. ,The keyboard shown in Fig. 3 and adapted to themachine according to Fig. 5 is provided with hammers 25, each of whichcarries two characters, as shown in Fig. 9.

Fig. 15 shows in perspective a stenographic machine provided with akeyboard as shown in Fig. 4, the details ofwhich have been describedabove. This form has two printingvpoints according to Fig. 7 and isprovided with hammers carrying three letters or charac- Yters, as showninFig. 10. -The same stencgraphic machine could be used for the English,French, German, Italian, or otherlanguages by adapting thereto asuitable keyboard and with a sufficient number of keys, according to thephonetic elements to belrepresented. Keyboards such as those .fdescribed above can also be adopted. For the designation of figuresconventional :letters could be adopted, chosen, preferab.ly,.in the samegroup of keys and placed between .two dashes, for instance, in order tofacilitate; dis tinction. The system of leversdesignedwto transmit themovement of. the shift-key 1'0, Figs. 3 and 5, will also beseen-bydotted lines in Fig. 11 and full lines in Figs; 12 and: '13, suchvmovement being, transmitted to the plate which supports thehammercarrying the exactly at the height of the-.printingmoint,

Fig. 6. This arrangement is, moreover,,s1m1- lar to that used for thesamepur ose'in typewriting machines-with several 0 aracters on the onekey. In each machine the keybcard is simultaneousl operated-Withthefingers of the right an left hand. Fen- .thearke board shown in.Fig.2 thefingers lowenj t e keys corresponding to the phonetic elementsof which the syllable is composed. The levers are actuated and made1130. advance the hammers carrying the-characters toward theprinting-point .to strike the inking and tlie printing ribbon. lhe.syllable is printed, and under the action ofsprings 27;0he keys riseagain. and return the hammers-carrymg the characters to theiroriginaliposition.

Duringthis. time .the:.printingeribbonncontinues to unwind,..so thatitpreeentstqthe printing-points a fresh portion fOI'kthfi printing ofthefol owing syllables, and theillklllg-flibhon isdisplaced. in, theccntrary'dimzcticn.

At :the same time the hammers area-displaced,

IIO

as explained above, and the rintin is. conveniently brought about. en t'e shift key is then released, the parts return to their normal positionunder the simple action of gravity.

In certain cases a simplified keyboard for only one hand could be used,as shown in Figs. 16 and 17, comprising two series of keys i,- videdinto four groups, each having its own printing-point. This form isoperated by the combination in printing of signs of one or the;

other series in order to obtain new characters. For instance, with n andv, m will be obtained by putting'b'oth together, with c and j printedand 'oined to ether g.-

will be obtained, .0 an i give a, and so on. p y

The different parts above described can be used. in certain cases incombination with' other or ans of existing type-writin machines, w liichwill be thus transforme into stenographic machines.

Having thus described my invention, what I claim as new 1s- 1. Astenographic machine, havin a com-- plete keyboard comprising four susidiary and separated keyboards, one of joint consonants, one ofmodifiers, one of vowels, and one of modifiers of said modifiers,'alurality oi groupsof type-carrying hammers, evers to actuate and toadvance the said hammers toward the printing-point to strike the inkingand printing ribbon, said keyboard having four printing-points, so thatwhen certain nants, one of modifiers, one of vowels, and

one of modifiers of said modifiers, a plurality of groups oftype-carrying hammers, levers to actuate and to-advance the said hammerstoward the printing-point to strike the inking and printing ribbon, saidkeyboards having four printing-points, so that when certain keys arestruck, the hammers carrying the corres onding characters aresimultaneously place and simultaneously print the proper honeticsyllables, a shift'key and a system of evers for transmitting movementthereto.

In witness whereof I have hereunto set my hand in presence of twowitnesses.
